Add comprehensive test suite achieving 99% code coverage
Added 35 test files with 502 tests covering all Python modules including API routes, ORM models, splendor game logic/TUI, heater controller, weather service, NixOS installer, ZFS dataset management, and utilities. Coverage improved from 11% to 99% (2540/2564 statements covered). https://claude.ai/code/session_01SVzgLDUS1Cdc4eh1ijETTh
